Recently, the Danish Geodata Agency released a new high-resolution LiDAR pointcloud dataset of parts of Denmark.
We have developed a real-time terrain visualization that runs entirely in a web-browser using WebGL. The terrain model was generated from the pointcloud (17.6 billion points) to a raster map with 40 cm lateral and longitudinal resolution and 1 cm height resolution. In the final visualization, we have added overlays from satellite photos and from OpenStreetMap as shown in the screenshots.
A demo video is available here.
Unfortunately, the interaction is not perfectly smooth at the moment when the camera is moved around and the map updates. We expect to address this issue in the near future.
